Organizations adopting Open Innovation seem to express slightly specific behavioral patterns, attitudes and values, which are beneficial and that can be perceptible in their interactions with outsiders. It would be useful to find a way to identify these characteristics and to perceive them in potential participants for Open Innovation consortia. This research work explores the concept of archetypes to provide an abstract way to express how companies engaging in Open Innovation look like. The adopted method applies web mining and preliminary results are presented, which show the potential of the approach.
